I have a T989 that's been hard bricked for some time now. I wasn't interested in sending it out for JTAG because it was just a backup phone and it served its purpose. When it was working, it was a great phone.
Recently I came across a thread (http://forum.xda-developers.com/show....php?t=2439367) that shows how to unbrick a T999 (T-Mobile Galaxy S3) that shows QHSUSB_DLOAD without JTAG. (QHSUSB_DLOAD shows up in device manager when I plug my phone via usb.)
My question is, could this solution posibly work for the T989?
Thanks in advance.
